помогите пожалуйста ​

Answer 1

Ответ:

3/4

Пошаговое объяснение:

1) 3 1/4 + 2 1/6 = 3 3/12 + 2 2/12 = 5 5/12

2) 5 5/12 : 2 3/5 = 65/12 : 13/5 = 65/12 * 5/13 = 5/12 * 5/1 = 25/12 = 2 1/12

3) 5 1/6 : 31 = 31/6 * 1/31 = 1/6

4) 2/3 : 4/9 = 2/3 * 9/4 = 1/1 * 3/2 = 3/2 = 1 1/2

5) 1/6 + 2 1/12 = 2/12 + 2 1/12 = 2 3/12 = 2 1/4

6) 2 1/4 - 1 1/2 = 2 1/4 - 1 2/4 = 1 5/4 - 1 2/4 = 3/4
